A partial panorama overlooking Kiluea Crater. Kiluea is the third highest mountain on the Big Island, but you can't tell that your very high up looking across the expansive caldera. The smaller crater below is called Little Kileua Crater, where the last eruptions took place 30-40 years ago. Current eruptions, which have gone on without a stop for 20 years or so, are coming out of a rift zone along the eastern flank of the mountain, and lava continues to flow into the ocean every day.
